Subject Re: [jira] Commented: (SOLR-1301) Solr + Hadoop
Date Fri, 15 Jan 2010 20:14:22 GMT
The reason I would a major speed win when expect indexing to local disk and
copying later is that you get much more efficient reading of documents with
normal hadoop mechanisms.  Throwing documents to the various Solr master
indexers is bound to be slower than having 20 machines reading at local disk
speeds if only because of network delays.
